Sounds like the way to go.
The Plus version has the advantage of the All Sky Map which you can see in my screenshot. It's basically photographs of the sky mapped into the software. I think it only makes it look pretty (if you have older machines it can slow down a bit -- you are able to change the level of quality for accuracy or for speed) and also helps you guage how big objects really are instead of just looking at outlines as a guide. If you're not too fussed about having the All Sky Map and just want to be able to find things, as well the ability to control your telescope from the comfort of your laptop/PC, you can go for the Pro version as you've highlighted.
Having said that, you could just stick with Stellarium or Cartes du Ciel if you just want to be able to find objects. Best part about those are that they're free.
Hope this helps somewhat!
